Humans breathe out CO2 (Carbon Dioxide) and plants breathe this in and produce 02 (Oxygen) which we in turn breathe back in again.

∙ 7y agoYes. Oxygen is used in the oxidation of carbohydrates, fats and proteins. Oxidation releases energy to carry out cellular activity. The by-products of carbon based fuels (including food as a fuel) is mainly carbon dioxide.
CO2, Oxygen, nitrogen, water vapor, etc. but CO2 is at a higher percentage

∙ 8y agoPeople breath air, not oxygen. Breathing pure oxygen have be hazardous to health.
Air is a mixture of oxygen, nitrogen and a small amount of many other gasses. Some of the oxygen in the air that people breath in is separated from the rest of the air in the lungs and circulated through the body in the blood.

∙ 14y agoWe breath air, which is a mixture of nitrogen, oxygen, carbon, and a few other elements. If we breath straight oxygen, we tend to pass out.

Does trees absorb carbon monoxide?
Carbon Monoxide: is a colorless, odorless, tastless gas that when inhaled is toxic to humans. Carbon Monoxide: is a byproduct of a rich mixture fire, Burning wood, Gas fires, etc. Your answer is No! Trees use Carbon Dioxide which is what you release when you exhale. So-Live long.
What gas do humans need to breathe in order to live?
Oxygen we inhale oxygen and exhale carbon dioxide
Do humans inhale carbon dioxide?
Humans breathe in whatever happens to be in the air when they breathe in. If there is carbon dioxide then they will breathe it in as well as nitrogen and oxygen. However they only use the oxygen for respiration so they breathe out everything else with extra carbon dioxide.
Do humans exhale only carbon dioxide?
we also exhale water(h2o) along with carbon dioxide. All the constituents of the air we inhale are in the air we exhale. The proportions differ because of the gas exchange in the lungs.
What gas do people breathe out?
Humans breathe in oxygen and exhale carbon dioxide. Plants take in this carbon dioxide along with sunlight and water, and convert it into a form of energy. They release oxygen.Carbon dioxide CO2
What is a declarative sentence for exhale?
Humans breathe out carbon dioxide and water vapor when they exhale. The relaxation of the diaphragm muscle allows you to exhale, but tightening the chest muscles lets you push air out forcibly, as when inflating a balloon.
Can people be effected by carbon monoxide released from gaseous systems that are for extinguishing a fire?
Carbon monoxide is flammable so is not used in fire extinguishing systems. The carbon dioxide that is used in extinguishers can be deadly to humans as it displaces oxygen that a fire needs to burn, and humans need to breathe.
Is cow realese oxygen during breathin?
No, PLANTS release oxygen when they breathe. Cows, like humans, release CARBON DIOXIDE when they exhale.
Which gas do humans exhale?
Carbon dioxide
What does the human exhale and inhale?
Humans inhale oxygen and exhale carbon di oxide.
How do chameleons breathe?
Chameleons have lungs and air passages much like humans do. They inhale oxygen and exhale carbon dioxide like all other reptiles.
Do humans breathe air?
your diaphram contracts and you inhale the air then the air goes to your lungs where it goes throughout your blood stream then the old oxygen picks up the carbon and then you exhale the oxygen with the carbon
